Grinding feeling from rear wheel

[Grumpy Goat]

They had a look at the shaft drive and after not finding anything strange they decided to try and fit another tyre to see if that is the issue and well long story short, it was.

... I don't like Angel GTs all that much and tend to get rid of them soon after purchasing a "new" motorcycle.

PS. They fit a Diablo Rosso Corsa (newish 2nd hand), which I'll be throwing away soon. It might not "vibrate" but it starts slipping as soon as it hears about moisture on the road.

Thanks for updating the thread, and glad to hear that it is resolved. Tire vibration did not even enter my mind.

Are Pirelli Angel GTs factory fitted on RSs in your neck of the woods, or were they put on afterwards? And their fitted replacement was another Pirelli tire ... sounds like the dealer may be pushing Pirelli tires..? I have Diablo Rosso Corsa tires on my S1000R and while I cannot definitively say that they are slippery in wet conditions, I do know that they are more "slippy" when not yet warmed up than my preferred Michelin or Dunlop tires. I very much doubt that I will be replacing them with another set when this set is done. And they are not cheap either.
